BARREL CLEANING APPARATUS Filed Nov. 1. 1928 2 Sheets-Sheet 2 Imnentor A.N.Eat0n attorney Patented July 8, 1930 PATENT OFFICE ALBERT N. EATON, or oivrAHA. NEBRASKA BA EL cLEANIN APPARATUS I Application filed. November The present invention relates to improvementsinbarrel cleaning apparatus, and has for an object-to provide an improved appa ratus for cleaning the rust, scale, grease, old paintand other foreign-substances from-barrels, particularly metal barrels. I

' Anotherobject of the invention is to provide an improved apparatus ofthis character in which the cleaning of the barrels may be conducted economically and efiiciently.

A furtherobject of the invention is topro vide an improvedapparatus,.wherein barrels of different diameters may be cleaned witha out requiring any modification of the constructions of the. parts and by admitting the various. different types of barrels after minor adjustments have been made. I

A stillfurther object of the invention is to- I provide an improved barrel cleaning appa ratus inwhioh the parts are grouped into a compact construction, operating simply and reliably, and the construction and arrangement of the parts admitting of the barrels being quicklyplaced in, and removedfrom, 5 the apparatus. 4 V

Astillfurther object of the invention is to provide an improved barrel cleaning apparatus in which the cleaning operation .is reduced in point of time and the results achievedare superiorato those now obtainable with present typesof apparatus.

With the foregoing and other objects in View, the invention willbe more fullygde-.- scribed hereinafter, andwillbemore-particularly pointed out in; the claims appended In the drawings, wherein'like symbol'srefer to like or corresponding parts throughout the several views,

1 %eferring more particularly to the drawings, 10 designates a vat or' container of any desired form, for instance of the 'U 'for,m shownincrosssection, The vatis open'atits top I and provided with reinforcing angle irons il -along the margin portions ofits. side walls. The vat may be SUPP ITtedin. any appropriate manner, for instance by means of cradles 12 having thelegs 13 resting upon the. floor. Withinand adjacent the lowermost portion ofthe vat 10 is a steam pipe or coil 14 having its ends brought out, as indicated in Figure 1, and connected.witha-boileror other source'of steam supply (not shown), whereby a circulation of steamthrough the pipe 14 may be had to raise the-temperature of the cleansing solution in thevat 10.

This solution may contain chemicals, such as caustic soda and the like. :InFigure 1, a drainpipe 15 is shown. as connected to the vvat for the purpose of. drawin'gofi' thesolution at desired times andthe drain pipe. may be p'rovidedwith a suitable cut-off valve (not sh e Two shafts 16 and 17 are suitably-jour- I naled in theend walls of the, vat. and extend substantially the" entire length of the vat and preferably throughone of the end Walls, as shown-in Figures --1 .and 3, .where such shafts are respectively provided with qfixed pinions 18 and 19 disposed inmesh with an intermediate idler pinion 20, whereby the shafts lfiand 17. mayrotate in the same direction.'

5 I One of theishaft-spfor instance,the shaft 1 6 carries a. pulley-21 engaged by the belt 22, whereby-the shafts are driven. from any appropriate source fOf' power. Within the vat 10, is disposed. a; brush; shaft ZBca-rrying the; rotary brush 24, The shaft 23,is supported forx swinging movementiabout the shaft lfiasa center and for this. purpose the end portions of the shaft. 23am carried by. arms 25,; such as shown inFiguresl and: 5, while the intermediate; portions of the shaft 23 are -pivota1llymounted in triangular-plates 2 uch ass ow in ig re. The brush 24 ispreferably a still wire brush, and asshown loo 3 in Figures 1 and 2, two or more such brushes may be employed in the same vat 10, it being understood that the embodiment of the invention shown in the drawings is for the accommodation of two barrels whereby two such barrels may be washed simultaneously. The barrels are indicated at 27 and are adapted to rest upon the rollers 28 and 29 which are fixed to the shafts 16 and 17.

The triangular bracket arms 26, shownin Figure 4, are adapted to carry a counter shaft 30. Pinions 31 and 32' are splined to the counter shaft .30, the pinion 31 being disposed at all times in mesh with a pinion 33 fixed upon the shaft 16; and the pinion 32 being in mesh at all times with a small pinion 34 on the brush shaft 23. By this means it will be understood that a gear ratio is provided, whereby the brush shaft23 will rotate at a much higher speed than the drive shaft 16.

As best shown in Figure 4, a rod 35 depends into the vat and is connected at its lower end to an arm 36 having connection to one of the triangular frame plates 26. The upper portion of the rod 35 is provided with threads, as indicated at 37 to receive an adjusting nut 38 having an extension handle 39 for convenience in its rotation. The threaded portion 37 of the rod extends upwardly through a cross beam 40 disposed across the vat, and the nut 38 is adapted to rest upon this beam 40.

Upon the rear wall of the vat 10 vertical cleats 41 are secured and provided with a plurality of eyes 42 to removably receive the pins 43. The cleats are further provided with recesses 44, shown in Figures 4 and 5 to receive the pivot rods 45 of the hold-down frames or devices. These frames consist of the side styles or bars 46 and the transverse brace rods 47. Upon the side frame members 46 a pair of L-shaped arms 48 are secured and provided with transversely extending connecting rods 49.- One such rod 49 is positioned, when the device is in the raised condition, shown in Figure 4, to receive the hook or keeper'5O pivoted at 51 upon the bracket 52, carried by the vat or other appropriate part.

Attached to the side frame members 46 are plates 53 in which are carried pivot rods 54. Roller carrying frames 55 are pivotally attached to the plates 53 through the pivot rods 54, said frames carrying rollers 56. Each frame preferably carries four rollers, as shown in Figures 1 and 2.

In operation, the vat is filled up to a suitable level with a chemical or other cleansing solution. The steam may or may not be turned on through the coil 14 to heat this solution to a desired temperature. Initially the hold-down devices are in the raised position, shown in Figure 4, where they are held by the hooks or keepers 50, so that the undivided attention of the operator may be given to the work of introducing the barrels into the upper ends of the vats and onto the supporting rollers 28 and 29. It will be seen from Figure 1 that four such rollers are provided, two on each of the spaced shafts 16 and 17. These shafts being rotated in the same direction, will cause the barrel 27 to also rotate within the vat and within the solution. The hold-down devices are lowered upon the barrel to the position indicated in Figure 5, and the required pressure may be exerted upon these hold-down frames to keep the barrels against the rollers 28 and 29 and the parts will be released and the brush and its assembly will drop by gravity away from the barrel. "The degree of the pressure of the brush may be thus regulated.

' In Figure 4 I have shown'a barrel of large diameter, as'compa'red, in Figure 5, with a barrel of smaller diameter. It will be noted by comparison of these figures that the pivot bar 45 of" the hold-down device occupies a position in the cleats 41 one notch higher in Figure 4, than in Figure 5. The hold-down frame may be adjusted to any of the notches 44 by first removing the pin 43 and again inserting the pin in front of the bar 45, after the same has been deposited in the selected notch. In this way all standard sizes of metal barrels may be cleansed in the vat.

I do not wish to be restricted to the size, form and proportions of the various parts, and obviously changes could be made in the construction herein described without departing from the spirit of the invention, it being'only necessary that such changes fall within the scope of the appended claims.

What is claimed is 1. In a barrel cleaning apparatus, a vat, barrel supportingmeans in the vat, barrel cleansing means in the vat, a notched bracket, a pin for closing the notches, and. a pivoted hold-down device for the barrel having a rodto selectively fit in the notches of said bracket and held 'removably therein by said pin. r

2. In a barrel cleaning apparatus, a vat, barrel support and brushing means therein, brackets, a hold-down frame'adjustably and pivotally held by said brackets, a catchto hold the frame elevated, and a supplemental roller frame carried by said hold-down frame. 1
